损耗和非线性是影响超100 Gbit/s高速光通信系统性能最为关键的因子。文章设计并研制了一种适合400 Gbit/s高速传输用的新型单模光纤, 该光纤具备超低损耗与超大有效面积特性, 在1 550 nm波长处衰减为0.165 dB/km, 在1 625 nm波长处衰减为0.179 dB/km; 在1 550 nm波长的模场直径为13.96 μm, 有效面积为153 μm2。该光纤具备优良的抗弯曲性能, 其关键技术指标优于当前国际技术水平, 可为下一代高速光纤通信提供关键基础材料支撑。
Abstract
Loss and nonlinearity are the most critical factors affecting the performances of 100 Gbit/s optical communication systems. This letter designs and develops a novel single-mode fiber for 400 Gbit/s high-rate transmissions. With ultra-low-loss and super-large effective area characteristics, its attenuation coefficients are reduced to 0.165 dB/km at 1 550 nm and 0.179 dB/km at 1 625 nm respectively. The mode-field-diameter is 13.96 μm at 1 550 nm, and the effective area is 153 μm2. Moreover, this fiber has outstanding anti-bending performance and its key technological specifications are superior to the current international technological level and can provide the key fundamental material support to the next generation high-rate fiber-optic communications.
